Great handling starts with a superior frame. The CRF450RX’s chassis was designed to be narrow, lightweight, and more responsive thanks to reduced lateral rigidity. The result is a bike that gets into, around, and out of corners faster.
The CRF450RX includes the first hydraulically actuated clutch we’ve offered outside of our works bikes. Made by Nissin, it’s the same design as in our Grand Prix MX machines, and performs better than third-party conversions. You get a clutch-lever pull that’s ten percent lighter at its peak, even though it’s paired with a stronger clutch. Plus, you’ll never have to worry about making a clutch-cable adjustment, even during the longest events.
The air filter and airbox shape are designed to help deliver more torque. You can access the airbox through the left number plate. And because the filter has no rubber gasket where it interfaces with the intake boot, cleaning and servicing the filter is faster and less messy than ever.
The CRF450RX’s Dunlop Geomax tires are specially designed for Enduro use. The AT81 tires are spec’d at 90/90-21 for the front and 120/90-18 for the rear. You read that right: the CRF450RX rolls on an 18-inch rear wheel.
